Okay, I have to admit that I haven't played with my Dillon since the move about a year and a half ago, so I'm hazy on what my problem was. When I start up again, I'll go through the manual and set up procedures from the start.

I just remember that when I first got the press, I either ran out of primers or cases or some combination that caused power to be spilled which then necessitated taking the shell plate off to clean the powder up under it. It was a pain in the neck and only occured when switching calibers and setting up the powder measure to drop the right volume. I now have two powder measures and plan to dedicate one to .223 and the other to whichever pistol cartridge I'm shooting the most at the moment. I also plan to get one of those non-hysteresis adjusters for the powder measures - I assume they are now on Dillon's website (I haven't hit it since long before the move either).
